TECHNICAL FIELD
[0001] The present application relates to the technical field of motor production equipment, and in particular to a rotor lamination inclined slot magnetic steel assembly mechanism for a mining explosion-proof motor. BACKGROUND
[0002] The mining explosion-proof motor is an electrical device specially designed for flammable and explosive dangerous places such as coal mines, and its core feature is to have an explosion-proof housing that can effectively withstand internal explosion pressure and prevent the spread of fire and explosion energy to the external environment, thereby ensuring safe operation in dangerous places. When the motor is connected to a three-phase alternating current power supply, a three-phase symmetrical current flows through the three-phase stator winding, generating a rotating magnetic field. The magnetic field and the rotor conductor produce relative cutting motion, thereby generating an induced electromotive force and an induced current in the rotor conductor. Under the action of the induced electromotive force, the induced current is generated in the rotor conductor, which is then subjected to electromagnetic force, forming an electromagnetic torque to drive the motor rotor to rotate along the direction of the rotating magnetic field, and finally output mechanical energy.
[0003] The following problems exist: The common mining explosion-proof motor housing has good waterproof, dustproof, shockproof and anti-collision functions. When the housing is installed and disassembled, the worker needs to turn a plurality of groups of nuts in sequence, so that when the magnetic steel in the motor is replaced, the worker needs to spend a lot of time in the whole process, and it also hinders the normal use of the explosion-proof motor.
